KNITTING MACHINE FOR THE MANUFACTURE OF OOBSE'IS AND Application filed Kay 28, 1928, Serial No. 840,997, and in France June 28, 1988.

The present invention relates to improve-- ments in a straight knitting machine of a. known type, utilized in the manufacture of hosiery goods and more particularly of elastic hosiery.

In said type of machine a thread (generally a rubber thread) is distributed along the fabric between two successive rows of meshes and passes alternately over and below the adjacent meshes. For this purpose, the machine comprises opposite the usual row of needles, :1 row of longitudinallymovable fashioning points which are arranged opposite every second needle, said fashioning points being adapted to cover at certain times of operation the operative ends or books of the corresponding'needles, in order to receiveand temporarily support one half of the meshes in formation. 7

In such known machines, as constructed heretofore it was practically impossible to make narrowings or widenings in the middle part of the knitted work, i. e. to diminish or increase the number or meshes or loops in the successive rows symmetrirally with respect to the vertical median line of the work. For this purpose, it would be necessary to transfer by hand the different loops from certain needles to other needies, which of course, would require consid erable handskill, time and attention and be practically impossible. One object of the invention is to provide a machine of said type with an im roved fashioning device by means of which t e operator is enabled to perform the aforesaid operations in an easy and ra idma-nner.

In the accompanying rawing which shows by away of example a constructional form of the invention mounted on a hand knitting frame of the above mentioned type.

tion showing the relative positions of the main parts coo rating in the making of the stitch; in said figure and'for the sakeof clearness, the main and auxiliary fashioning points are shown at slightly different heights.

Figs. 5, 6 and 7 are partial transverse sections respectively along lines 55, 66 of Fig; 3 and line 77 of Fig. 2.

Fig. 8 is a plan view with parts broken away of another constructional form of the device according to the invention.

Fig. 9 is a sectional view along line 9-9 of Fig. 8.

Fig. 10 is a sectional view along line 1010 of Fig. 8.

Figs. 11 to 19 show diagrammatically the successive steps in the manufacture of straight parts of the knitted goods.

Figs. 20 to 25' show in the same manner the successive steps of a narrowing operation.

. By means of the im roved machine described below it is possi le to obtain knitted articles, such as that shown diagrammatically in Fig. 1, i. e. a piece of knitted fabric in which the number of meshes is progressively reduced from the initial or bottom row of meshes up to the final or top row, the reduction or narrowi in the middle of the lengt of the piece. The piece is 'shown in Fig. 1 as it a pens when suspended to the row of vneetfies of the machine, diagrammatically shown at 26.

It will be seen that such iecc of hiitted fabric comprises in its mid le lower part a swelling portion which will fit upon one hip of the wearer when said piece is used to form one lateral half'of a" belt orrcorset. When spread on a plane surface, the said iece would assume the shape shown in As shown more clearly in Fig. 4, the machine comprises as usual :1 horizontal stationary needle bar 2 carryin the horizontal needles 26 rovided at their end with the usual flexi le hook. Between the needles 26 are vertically placed the sinkers 27 which as usual are provided with a slot 28 and are moved vertically and also horizontallLinb;

direction at right angles to the needle 1 foot or hand operated mechanism not shown. Opposite every second needle of the mwiaplecedahonzontalfadnmmngpoint taking place 10. In the known constructions the series of fashioning points 10 is directly carried by a longitudinal carriage 4 (Figs. 2 and 3) which is provided at its ends with trunnions 3 engaged in suitable slots 3 (Fig. 7) pro: vided in horizontal arms 1 carried by the needle bar 2. Said carriage 4 is provided with a handle 5 by'mcans of which a horizontal reciprocating motion in a direction at right angles to the needle bar and at the same time a rocking motion about the trunnions 3 may be imparted thereto and consequently to the row of points 10. The

points 10 are thus able to come over the hooks of the corresponding needles as shown in Fig. 4. A presser bar 42 may be periodically lowered upon the points 10 so as to press them upon the hooks and thereby hold the latter-in the closed position.

Inaccordance with my invention, the device above described which is of a known construction, is completedas follows: The usual fashioning points 10, which I shall term the main fashioning points are not directly mounted on the carriage 4 and are carried by two sliding supports 8 and 8 which are longitudinally guided in the carriage 4 for instance by means of dovetail grooves (Figs. 4 and 6) whereby they can be moved parallel to the needle bar and in opposite directions to each other according to the arrowsti and 7 (Fig.2.) The fashioning points 10 are placed in transverse grooves formed in the upper face of a longitudinal bar 11 having vertical apertures 9 (Fig. 2) for receiving the tails of said fashioning points,.the latter being thus disposed in a row in front of the needles 26 and spaced apart by two needle-divisions. baid bar 11 is provided between the succes- 'sive main fashioning points, with slots 12 in which auxiliary fashioning points 13 secured to s1ides 14, 14 are slidable, said auxiliary fashioning points being thus placed opposite every second needle 26 of the bar. Said slides 14, 14' are adapted to slide upon 'eaeh of the movable supports 8 and 8" towards and away from the needle bar so as to bring the operative endsof the auxiliary fashioning points 13..inra1ignment with the operative ends of the main fashioning points 10 or to draw back the former with respect to the latter. The grooved bars 11 are fastened to the-supports 8, 8 by means of cover plates 48 and 48' suitably secured to said supports,

for instance "by means. of screws 49. The

slides 14 and 14' are moved towards and away from the needle bar by the tappets 15" (Fig. 4) which engage the slots 16 in the "slides 14, 14' said slots being suitably elongated so as to permit the motion of the slides together with the point supports 8, 8 in the direction of the arrows 6 and 7 or in the reverse direction, thei-tappets 15 are secured to a rod 17 which is revolubly mounted in supports 19 secured to the carriage 4, and adapted to be turned in either direction by means of a handle 18'.

In the middle of its length, the carriage 4 is provided on its upper face with a boss 20 (Figs. 2'and 3) which is situated between the supports 8 and 8.

A rotatable cam or eccentric 22 which r0- tates on a vertical pivot 21 carried by said boss is adapted to act upon two blocks 23 and 24 each of which is secured to one of the movable point-supports 8, 8. A coil spring 25 holds the blocks in contact with the cam. The stationary boss 20 carries a set of main fashioning points 10' having the same spacing as the main fashioning points 10; when the auxiliary fashioning points 13 are moved backward and the movable point supports 8 and 8 are brought into contact with the boss 20, the main fashioning points 10, 10 are disposed throughout the whole length of the apparatus along a continuous line with a constant spacing equal as above stated to two needle divisions, and in these conditions as later described, the mechanism may be used as in the ordinary machines.

The operation of the apparatus will now be explained with reference to the diagrams of Figs. 11 to 25 in which, for the sake of elearness, the fashioning points 10, 10 and 13 are shown slightly below the corresponding needles.

1. Illanufactare of the straight parts of knitted g00ds.-For the manufacture of the straight parts, the machine operates as ordinary knitting frames of the same type. The

is one main fashioning point opposite everysecond needle in the row.

Assuming that a row of meshes or loops has just been finished and is suspended from the needles 26 (Figs. 11, 11) the operator moves the'carriage 4 towards the needles whereby the main points 10, 10' come over thehooks of every second needle and close them. The sinkers move then the whole fabric towards the points 10, 10' and half of the loops are thus transferred upon the points, the other half being retained upon the needles having no points opposite themselves (Figs. 12, 12"); The operator then places a fresh length of the thread upon the row ofneedles and forms an additional row of loops. This row will be formed only on the needles from which meshes have not been transferred to the fashioning points i. e. upon one half of the needles. This formation of meshes is performed as usual by the combined vertical and horizontal move ments of the sinkers. Figs.:13, 13" show the said operation being performed m1 Figs. 14, 14' show the position of the parts when the operation has been effected.

The operator then places an auxiliary- -thread 43 (which as a rule is an elastic thread), between the needles 26 and the fashioning points, that is into the V-shaped channel formed by the loops depending from the needles and those depending from the points (Figs. 15 and 15). Now the main fashioning points are moved to wards the needles into engagement with the same, and, by means of the sinkers, the loops carried by said points are drawn onto the corresponding needles, as shown in Figs. 16 and 16.

The operator places a fresh length of the ordinary thread on the needles 26 (Figs. 17 and17) between the loops and the hooks of said needles, and, by actuating the sinkers and the presser bar, as usual, a new row of loops are formed on the needles (Figs. 18 and 18), and the following operations proceed as from Fig. 10. The workthus obtained has the structure shown diagrammatically in Figs. 19,19. I

. 2. Narrowing operation.

When a narrowing is to be done, the auxiliary fashioning points 13 are moved for:

ward with respect to the main points 10 and 10' by actuating the handle 18, so as to come into alignment with said main points 10 and 10'. The operator turns the cam 22-, thereby moving the sliding sup orts 8 and 8' away from each other, in tie direction of the arrows 6 and 7, this displacement of each support being e ual to one or more needle divisions accor ing to the extent of narrowing desired. In the drawing the narrowing has been su posed to be equal to one needle division. The carriage 4 being thus ready to operate is moved towards the needles so that\the mainpoints 10, 10' and auxiliary points 13 come over the hooks of all the needles 26. By actuating the handle 5, all the points are caused to ress upon the "hooks and close the same. he sinkers 27 being then moved horizontally towards the carriage 4 will transfer the upper loops of the fabric and thereby the whole fabric onto the points 10, 10', 13, the fabric assing thus from the position shown in igs. 19, 19" to that shown in Figs. 20,- 20". The carriage 4 is then moved away from the needles and, by rotating the cam 22 so that it comes back to its original position shown in Fig. 2, the sliding supports 8, 8 carrying the fabric on their points 10, 13 are allowed to move towards each other under the action of the spring 25 whereby all the loops on the points 10 and '13 are shifted by one division towards the middle of the machine.

The carriage 4 is then moved towards the iliary fashionin their slots 28 and the sinkers being then moved away from the carriage 4 willact to draw the upper loo 5 and thereby the whole fabric onto the nee les. The loops are now in the position shown in Figs. 21, 21*. The

narrowing operation is thus effected. The carriage 4 will then be retracted and the auxiliary points 13 will be restored to their inoperative position by means of the handle 7 p the improved device is used for effecting a symmetrical narrowing of the work on either side of a. narrow middle portion, the

small width of which is'determined by the I number of fashioning points 10 carried by the boss 20 of the carriage 4.

In the modification shown in Figs. 8, 9, 10, the movable point-supports 8 and 8 carrying the main fashioning points 10 engaged in the holes 39 of the said supports are provided with transverse slots 12 wherein the main fashioning points are disposed, and with similar slots 12 wherein the auxiliary fashioning points 13 are slidahle; these auxpoints have apart 30 which is bent an engaged in a. slot 31 of the slides 32, 32' adapted to slide on the pointiupports 8 and 8 transversally to the needle- These slides 32 and 32' are guidedbetween the stop-members 33 on the carriage 4, and the central boss 20 on said carriage, insuch manner that said slides cannot move longitudinally. The are further provided with flat studs 34 a apted to slide within guides '34 secured to the carriage 4. The slides 32 and 32 are actuatedfiiy means of a handle 18 secured to a shaft 17 rotatably mounted on the supports '19 secured to the carriage 4. Upon. this shaft 17 are keyed the tappets 35' which engage a suitable longitudinal chan' nel 35 of the slides 32, 32.

The cam-22 is mounted, as in the first construction described. on the central boss 20 of the carriage 4 and is ad: ted to actuate the two blocks 23 and 24. raid blocksare resectively secured to the supports 8 and 8' tlirongh the intermediary of the covering ieces 36 secured to thepoint supports 8, 8'

y means of suitable brackets 44. ()u said covering pieces are secured brackets 37 which in turn hold the'comhs 38 whose teeth are engaged in the slots 12, 12' of the supports 8 and 8' in order to accurately hold the fashioning points.

The operation of the device shown in Figs. 8, 9 and 10 is the same as that of the apparatus shown in Figs. 2 to 7.

Various constructional modifications in detail may obviously be made in the apparatus described without departing from the invention.
